referenced toolbox part

I have 1 part that was created from the toolbox and is now referenced in an assy. Currently we check in all of our hardware and purchased parts for revision control, unfortunately this part was not converted before the main assy was checked in. I know how to use the toolbox convert utility to change the status, but how do I remove the reference in the vault and check in the file? I saw that you can login into the SolidWorks Workgroup PDM VaultAdmin as an admin (I am) and delete the toolbox ref, but I can’t seem to find it anywhere and the vault will not let me change the project or check out the file.

Thanks,

Mike
